LD-PD's Integrated Polarization Beam Combiner and Depolarizer(IPBCD) is used in Raman or Hybrid Raman/ED- FAs.The function is to combine two pump lasers into one,which also has an Isolator to protect pump laser and scram- bling the polarization of light to improve amplifier efficiency and performance within a single,compact-sized cylinder package.This product has low Insertion Loss,low DOP,etc.

Notes:

1. All values referenced without connector.

2. The input optical polarization direction is aligned to the slow axis.
